As explained in "Mac OS X 10.2 Welcome and Install Manuals" and "Mac OS X Welcome and Install Manuals", you may need to update the firmware on your Macintosh computer prior to installing Mac OS X 10.2 or later. The following table lists the firmware updates that are available for Apple products that can update to Mac OS X 10.2 or later.
Note: Rows in PINK indicate computers that can install Mac OS X 10.2 but are not supported with Mac OS X 10.3, 10.4 or later.
If you are unsure whether your computer needs a particular update, simply download and open the update installer. If the update is already installed or not needed, the installer will alert you to this.
Important: These firmware updates cannot be installed when the computer is started up from Mac OS X. In order to install them, you must start up the computer from a Mac OS 8 or Mac OS 9 System Folder on the computer's hard disk (not from a CD). See the hardware and software requirements listed for each installer for details.
